IMPROVEMENT IN FAUCETS.

"Specification forming part of Letters Patent No. 35,450, dated June 3,1862.

To all wtom, it may concern.- Y

Be it known that we,JAcoB JAHRAIIS and JOHN GEORGE BicKEL, of the city of Buffalo, county of Erie, and State of New York, have invented anew and Improved Beer-Faucet; and we do hereby declare that the following is a full,

clear, and exact description thereof, reference being had to the accompanying drawings, and' zle opening downward.

B represents the key or plug fitted and operating in a common manner.

C represents ,the cylinder of a small forcepump or syringe, passing through the nozzle and projecting aboveand below. It is of less diameter than the nozzle, so as to leave an annular space around it through which the beer v `or liquor may issue when the key is properly turned. i

D represents a piston `or plunger placed Within the cylinder and having a spring, e,

Vcoiled around it, which spring bears against the shoulder f atthe top of the cylinder and the collar g on the lower end of the plunger,

' sothat when the plunger is drawn up in the cylinder the spring will be compressed, and by its elasticity force the plunger down again very quickly. The plunger is made to move tight in the cylinder by the packing h, held between the collar g and the nut or follower t'. It has a knob or button, j, on its upper end, by which it is raised.

k is avalveseat screwed into the lower end of the cylinder, and Z is the valve. A small hole, m, is made through the center of the valve,out of which the liquor which is drawn into the cylinder by the upward movement of the plunger is forced by its downward movement. l y

Theoperation of this combination is as follows: All kinds'of beer and ales lose their flavor and taste by exposure to the air, and it is necessary to make them run freely from the cask to admit a certain quantity of air into its top. This give them a fiat and insipid taste, especially when drawn off in small quantities at intervals, as in glasses. A glass being held under the nozzle of the faucet, the faucet is opened by turning the key until the glass is filled and then shut again. Before taking away the glass the plunger of the pump is drawn up, causing the valve to lift and the pump to till itself from the liquorin the glass, which, when the plunger is forced down by the spring,will be injected back into the glass with great force through the small hole in the valve, causing the beer or ale to foam and sparkle and restoring completely itsflavor,

and even adding to it, so that the last glass drawn from the cask will have as good a davor as the first. l

n is a small tube screwed into the side of the faucet and opening'against the plug or key when the faucet is shut, but into a hole, o, drilled into the plug to its center and there meeting a vertical hole, p, drilled down through the handle ofthe plug,when the faucet is open. When the faucet is placed in a cask for use, a rubber tube, g, is made to connect the tube n with a vent-tube driven into the top of the cask, so that when the faucetis open a communication will be formed from the air to the inside of the cask, causing the liquor to run freely, and when the faucet is shut the communication is also shut, thus making a perfectly reliable self-acting vent.

To cause the vent to open at the same time that the faucet does, a groove, r, of the proper length, is cut inthesurface of the key, into which the hole o opens, the groove coming opposite the pipe n and opening the vent at the time the key-is turned far enough to allow the passage of the liquor through the faucet.

Weclaiml. The combination of a force pump or syringe with the faucet,when constructed and y JACOB JAHRAUS. J. GEORGE BIOKEL.
